There is.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc guard or a similar type wheel guard holding structure for an electric tool.

[0002]

[Prior art]

 When using a disc grinder, etc., it is necessary to install a wheel guard that covers more than half the circumference of the toy, and it is necessary to change the wheel guard installation position according to the work and application. It is a power tool with a high frequency.

Conventionally, attachment / detachment of a wheel guard such as a disc grinder requires the use of a spanner or a driver, which is troublesome and inconvenient.

[0004]

[Problems to be solved by the device]

 The conventional wheel guard holding structure requires tools such as a spanner and a screwdriver, which is troublesome and troublesome, and these tools are easily lost.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to carry out without using a tool in the process of holding a wheel guard such as a disc grinder.

[0006]

[Means for Solving the Problems]

 The above object can be achieved if the wheel guard can be held without using a special tool such as a spanner or a screwdriver.

Therefore, it can be achieved by providing the set ring of the wheel guard with a holding groove of the packing land and a rib that can be fitted and locked by the elastic force of the coil spring.

[0008]

[Action]

 In the wheel guard holding mechanism configured as described above, the holding groove provided on the packing land and the rib of the wheel guard set ring are fitted by the elastic force of the spring so that the rib does not fall out of the holding groove. , Packinglands can hold foil guards.

[0009]

【Example】

 One embodiment of the present invention is shown in FIGS.

A coil spring 2 is provided between the end surfaces of the packing land 1 and the set ring portion 3 of the wheel guard 4 which face each other. The elastic force of the coil spring 2 causes the rib 8 to engage the fitting portion 6 of the retaining groove 5. Fit it so that it does not fall off. Several fitting portions 6 of the holding groove 5 are provided around the entire circumference of the holding groove 5 so that the wheel guard 4 can be held at any position.

First, when attaching the wheel guard 4, the coil spring 2 is attached to the packing land 1, the set ring portion 3 of the wheel guard 4 is set to the upper side, and the rib of the inverted triangle shape provided in four places on the set ring portion 3 is provided. 8 are attached to the packing land 1 at four places. The coil spring 2 is pressed from the groove 7 toward the holding groove 5 while being compressed, and when the rib 8 comes into contact with the abutting surface of the holding groove 5, the wheel guard 4 is rotated to move the rib 8 8 and the fitting groove 6 are fitted together. Due to the coil spring 2, a force for fitting the fitting portion 6 of the holding groove 5 is always applied to the rib 8 of the set ring portion 3 and the wheel guard 4 can be held.

[0012]

[Effect of device]

 According to the present invention, the wheel guard can be attached / detached only by pushing the wheel guard and turning it, so that no tool is required for attaching / detaching the wheel guard, which is a simple design. Nevertheless, the same operation can be simplified.
