Abstract

The utility model relates to an auxiliary protecting cover for compound saws, which has double functions. The utility model can protect saw teeth and ensure use safety of operators; a linking lock device is opened by using the utility model in the conversion process of an operation mode of the compound saw; the utility model is composed of cavity box integration bodies formed by blocking boards on which butting heads and positioning feet are respectively arranged for positioning in time. When the utility model is used, a machine body is pressed down, two butting heads on the blocking boards are respectively used for supporting a baffle plate and a support rod; the support rod is separated form a table surface protective board; the blocking boards leave a push pin hole, a platform cutting table board is arranged at last; the push pin is inserted in the push pin hole for locking the machine body.

Description

Compound saw is assisted protective cover

The utility model relates to a kind of portable electric power tool, the part protective cover of compound saw, the compound saw that suitable especially hinge type platform is cut mesa structure uses, both sawtooth can be protected, guarantee that the operator is safe in utilization, can make compound saw in the transfer process of carrying out mode of operation again, must use it just can open the auxiliary protective cover of compound saw of interlock.

Compound saw in use, especially in working mode change when platform is cut pattern, if the user operates because of carelessness, dangerous accident will take place, so for safety, need add auxiliary protective cover during operation, cover sawtooth.And existing auxiliary protective cover does not have chain function, thus some operator, do not want to take the trouble, scheme laborsaving, be reluctant to use auxiliary protective cover during cutting on table, thereby do not reach the protection purpose, make and kept the safety in production into an empty verbiage.

The purpose of this utility model is: provide a kind of compound saw with dual-use function auxiliary protective cover, existing protective action, guarantee safety, can open interlock again and carry out routine operation.

The utility model is achieved in that the auxiliary protective cover of compound saw by whole composition of cavity box that coaming plate constitutes, answers back to head and angle and also be fixed with respectively on the described coaming plate, reaches angle.

Fig. 1. structural representation of the present utility model;

Fig. 2. working state schematic representation of the present utility model;

Fig. 3. the chain view of compound saw (not having auxiliary protective cover).

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

The whole elongated cavity box of auxiliary protective cover for being made of three coaming plates, respectively there is an angle (5) at the place, breach limit of coaming plate (2), (4) rear end.Answer back to (1) of one protrusion is arranged at coaming plate (2) top, rear end, has a bar shaped that links to each other with the bottom to answer back to head (3) on the front inner wall.

Platform on the compound saw is cut table top (7) and is connected on the framework (6) with bearing pin, platform is cut and also is fixed with table top backplate (8) under the table top (7), framework cover cap (9) is fixed on the framework (6), strut (11) is movably connected on the framework cover cap (9), one end of spring (10) is fixed on the strut (11), and end is fixed on the framework cover cap (9) in addition.

Baffle plate (13) is movably connected on the framework (6), and an end of spring (12) is fixed on the baffle plate (13), and end is fixed on the framework (6) in addition, and distribution hole (14) is arranged on the framework (6).

During use, auxiliary protective cover is placed on the lower table face of compound saw, and two angles (5) on it is inserted in the groove at work top rear portion, make auxiliary protective cover location (work top figure does not draw).

Depress fuselage then, meanwhile, on the auxiliary protective cover two answer back to head (1), answer back to head (3) jack-up baffle plate (13) and strut (11) respectively, make it rotate an angle around fulcrum, and make strut (11) break away from table top backplate (8), releasing is cut the locking of table top (7) to platform, and can free rotate along bearing pin, sets level platform at last and cuts table top (7).

Allow baffle plate (13) leave simultaneously and promote hole (14), just can open locking mechanism, will promote to insert and promote locking fuselage in the hole (14).

So just finished the conversion of the state of cutting from the state of cutting sth. askew to platform, in whole transfer process, protection puts in place, has guaranteed safe in utilization simultaneously.

The utility model is compared with prior art: because auxiliary protecting cover has dual-use function, can not only play protection Effect and in the working mode change process, must be used it, otherwise does not become convert task with regard to complete, Can't work. Thereby it is laborsaving to force the operator can't scheme in process of production, must take care, will prevent Protect putting in place, so just really played the purpose of protection safety.

Claims

1. the auxiliary protective cover of compound saw is characterized in that also being fixed with on the described coaming plate (2) and answers back to head (1), (3) and angle (5) the whole composition of cavity box by coaming plate constitutes, and is fixed with angle (5) on the coaming plate (4).

2. protective cover according to claim 1 is characterized in that the whole elongated cavity box of auxiliary protective cover for being made of three coaming plates, and respectively there is an angle (5) at the place, breach limit of coaming plate (2), (4) rear end; Answer back to (1) of one protrusion is arranged at coaming plate (2) top, rear end, has a bar shaped that links to each other with the bottom to answer back to head (3) on the front inner wall.
