TECHNICAL FIELD

[0001] The utility model relates to electric tool accessory field especially easy installation prevents the back leather of cracking. BACKGROUND

[0002] Electric tools are mainly divided into metal cutting electric tools, grinding electric tools, assembly electric tools and railway electric tools, common electric tools have electric drill, electric grinder, electric wrench, electric bolt cutter, electric hammer and impact electric drill etc., in the use process of these electric tools, a large amount of metal waste cutting often splashes everywhere, can cause certain harm to the operator, therefore need to install back leather on the electric tool to shield, the traditional back leather is usually single plastic layer or rubber layer, leading to the back leather to be easy to be influenced by external environment and produce corrosion in the long-term use process, thereby leading to the back leather to be easy to appear the phenomenon of cracking, and the traditional back leather is usually bolted and is more cumbersome and inconvenient, therefore still need to be improved. SUMMARY

[0003] The utility model discloses to solve the problem of above-mentioned, for this provides an easy installation prevents the back leather of cracking, including leather, main fixed plate and vice fixed plate, be provided with fixed bolt on the main fixed plate and be fixed with leather through fixed bolt, be seted up with the opening on the main fixed plate, install U -shaped hook in the opening, the U -shaped hook includes two feet, and the cross position of two feet is provided with rotating shaft and is connected with the main fixed plate through rotating shaft, and is provided with spring between two feet, the end of the foot is bent and has inserted foot, the vice fixed plate is provided with the slot, and the inserted foot is inserted in the slot.

[0004] As preferred, the leather includes a rubber layer, the rubber layer has a metal wire mesh adhered to both the front and back surfaces, and the metal wire mesh has a high manganese steel layer adhered to the surface away from the rubber layer.

[0005] The utility model discloses the beneficial effect is: the utility model discloses the structure design is reasonable, convenient to use, can install or replace back leather fast, and the utility model discloses can improve the overall strength of back leather simultaneously, makes back leather not easy to appear the cracking. BRIEF DESCRIPTION OF DRAWINGS

[0006] The utility model will be explained through example and with reference to the mode of the accompanying drawings, wherein:

[0007] Figure 1 It is the whole structure schematic diagram of the utility model;

[0008] Figure 2 It is the back leather cross section structure schematic diagram of the utility model;

[0009] In the diagram: 1. Baffle; 2. Main fixing plate; 3. Fixing bolt; 4. Rotating shaft; 5. Support leg; 6. Spring; 7. Secondary fixing plate; 8. Pin; 9. Slot; 10. High manganese steel sheet; 11. Metal wire mesh; 12. Rubber layer. Detailed Implementation

[0010] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0011] Unless otherwise stated, any feature in this specification may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0012] like Figure 1 The diagram shows an easy-to-install crack-resistant rear cover, comprising a cover 1, a main fixing plate 2, and a secondary fixing plate 7. The main fixing plate 2 is provided with fixing bolts 3 and is fixed to the cover 1 by the fixing bolts 3. The main fixing plate 2 has an opening, and a U-shaped hook is installed in the opening. The U-shaped hook includes two legs 5. A rotating shaft 4 is provided at the intersection of the two legs 5 and is connected to the main fixing plate 2 by the rotating shaft 4. A spring 6 is provided between the two legs 5. The end of the legs 5 is bent into a pin 8. The secondary fixing plate 7 is provided with a slot 9, and the pin 8 is inserted into the slot 9.

[0013] like Figure 2 As shown, the shield 1 includes a rubber layer 12, and metal wire mesh 11 is glued to both the front and rear sides of the rubber layer 12. High manganese steel sheet 10 is glued to the side of the metal wire mesh 11 away from the rubber layer 12.

[0014] During use, the auxiliary fixing plate 7 is installed on the power tool with bolts, and then the main fixing plate 2 and the cover 1 are fixed with bolts. Then, by pressing the two support legs 5 inward, the distance between the two support legs 5 is reduced, thereby inserting the pin 8 into the slot 9. After the pin 8 is inserted into the slot 9, the pressing on the two support legs 5 is released, and the two support legs 5 are reset by the spring 6, thereby fixing the cover 1 on the power tool.

[0015] The metal wire mesh 11 can improve the overall strength of the baffle 1 and reduce the occurrence of breakage of the baffle 1; the high manganese steel sheet 10 can prevent external air from corroding the rubber layer 12, and on the other hand, it can also improve the wear resistance of the baffle 1.

[0016] The utility model discloses the beneficial effect is: the utility model discloses reasonable structure design, convenient to use, can install or replace rear apron fast, and the utility model can also improve the overall strength of rear apron simultaneously, so that rear apron is not easy to appear fracture.

[0017] The utility model discloses not limited to the preceding specific embodiment. The utility model extends to any new feature or any new combination disclosed in the specification, and any new method or process step or any new combination disclosed.
