Description

TECHNICAL FIELD

[0001] The utility model relates to electric wrench field, especially a kind of rechargeable electric wrench. BACKGROUND

[0002] Electric wrench refers to the electric tool of screwing and unscrewing bolt and nut, and it is a kind of tool for tightening high-strength bolt.Rechargeable electric wrench is a kind of wrench with battery, which can work by battery power without plugging in.Rechargeable electric wrench has high-speed rotating head and control switch for controlling the rotation of rotating head.The control switch of rechargeable electric wrench is directly exposed, without switch protection structure, and it is easy to cause the switch of wrench to be pressed by mistake, causing the electric wrench to start.Due to the high-speed rotation of the rotating head, if a child presses the start by mistake, there is a certain risk.In order to solve the above-mentioned problems, we propose a rechargeable electric wrench. SUMMARY

[0003] The utility model aims at providing a rechargeable electric wrench, which has the advantage of preventing the switch from being pressed by mistake.

[0004] The above technical purpose of the utility model is realized by the following technical scheme: a rechargeable electric wrench, comprising an electric wrench body, a support frame is fixedly connected to one side of the electric wrench body, a spring one is fixedly connected to one side of the inner cavity of the support frame through a spring fixing piece, a limiting seat is fixedly connected to one end of the spring one through a spring fixing piece, two limiting blocks are slidably connected in the limiting seat, a clamping groove is formed in the top and bottom of the inner cavity of the support frame and clamped with the limiting block, a spring two is fixedly connected to one side of the limiting block through a spring fixing piece, and the other end of the spring two is fixedly connected with the limiting seat through a spring fixing piece.

[0005] By setting the limiting block and the clamping groove to clamp the limiting seat, the limiting seat can be away from the control switch of the electric wrench body, which is convenient for the user to press the control switch of the electric wrench body; by separating the limiting block and the clamping groove, the limiting seat is moved towards the control switch of the electric wrench body, so that the limiting seat and the electric wrench body and the control switch of the electric wrench body are in contact, thereby preventing the control switch of the electric wrench body from being pressed by mistake when the wrench is not in use.

[0006] The utility model is further provided with a storage groove on one side of the limiting seat, and the spring one is located in the storage groove.

[0007] The above technical solution uses a storage slot to store the compressed spring.

[0008] The present invention is further configured such that the interior of the limiting seat and the support frame are slidably connected.

[0009] By adopting the above technical solution, the limiting seat and the support frame are slidably connected, and the limiting seat can move linearly under the guidance of the support frame.

[0010] The present invention is further configured such that the rebound force of the first spring is greater than the weight of the limiting seat, and the first spring is in a compressed state.

[0011] By adopting the above technical solution, the position of the limit seat will be limited when the limit block and the slot are engaged, and the spring will be in a compressed state. When the limit block and the slot are separated, the compressed spring will push the limit seat to move toward the control switch of the electric wrench body.

[0012] The present invention is further configured such that: a sliding groove is provided inside the limiting seat, and the limiting block slides inside the sliding groove.

[0013] The above technical solution uses a sliding groove to guide the limiting block and also to store the second spring.

[0014] The present invention is further configured such that: the second spring is located inside the sliding groove, and the second spring is in a compressed state.

[0015] Using the above technical solution, the second spring is used to support the limiting block. When the second spring is in a compressed state, it can push the limiting block into the inside of the slot. The rebound strength of the second spring in the compressed state is greater than the weight of the limiting block.

[0016] In summary, this utility model has the following beneficial effects:

[0017] This invention uses a limiting block and a locking slot to limit the position of the limiting seat, keeping it away from the control switch of the electric wrench body, making it easier for the user to press the control switch. By separating the limiting block and the locking slot, and pushing the limiting seat towards the control switch of the electric wrench body, the limiting seat comes into contact with the electric wrench body and its control switch. This protects the control switch of the electric wrench body when the wrench is not in use. When a child presses the limiting seat, the contact between the limiting seat and the electric wrench body prevents the child from pressing the control switch, thus avoiding accidental activation by a child.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A rechargeable electric wrench includes an electric wrench body 1. A support frame 2 is fixedly connected to one side of the electric wrench body 1. A spring 3 is fixedly connected to one side of the inner cavity of the support frame 2 via a spring fixing member. One end of the spring 3 is fixedly connected to a limit seat 4 via a spring fixing member. Two limit blocks 5 are slidably connected inside the limit seat 4. The top and bottom of the inner cavity of the support frame 2 are provided with slots 6 for engaging with the limit blocks 5. A second spring 7 is fixedly connected to one side of the limit block 5 via a spring fixing member. The other end of the second spring 7 is fixedly connected to the limit seat 4 via a spring fixing member. By setting the limit blocks 5 and the slots 6 to engage, the limit seat 4 is limited, allowing the limit seat to be positioned. 4 can be positioned away from the control switch of the electric wrench body 1, making it convenient for the user to press the control switch of the electric wrench body 1; by separating the limiting block 5 and the slot 6, and by pushing the limiting seat 4 towards the control switch of the electric wrench body 1, the limiting seat 4 comes into contact with the electric wrench body 1 and its control switch, so that when the wrench is not in use, the limiting seat 4 protects the control switch of the electric wrench body 1. When a child presses the limiting seat 4, the contact between the limiting seat 4 and the electric wrench body 1 limits the limiting seat 4, preventing the child from pressing the control switch of the electric wrench body 1, thus avoiding accidental activation by the child.

[0026] Furthermore, a storage groove 8 is provided on one side of the limiting seat 4, and the spring 3 is located inside the storage groove 8. The storage groove 8 is used to store the spring 3 in its compressed state (see...). Figure 1 ).

[0027] Furthermore, the interior of the limiting seat 4 is slidably connected to the support frame 2. Through this slidable connection, the limiting seat 4 can move linearly under the guidance of the support frame 2 (see...). Figure 1 ).

[0028] Furthermore, the rebound force of spring 3 is greater than the weight of the limit seat 4, so spring 3 is in a compressed state. With the setting of limit seat 4, when limit block 5 and slot 6 are engaged, the position of limit seat 4 will be limited, and spring 3 will be in a compressed state. When limit block 5 and slot 6 are separated, the compressed spring 3 will push limit seat 4 to move toward the control switch of electric wrench body 1.

[0029] Furthermore, the limiting seat 4 has a sliding groove 9 inside, and the limiting block 5 slides inside the sliding groove 9. The sliding groove 9 is used to guide the limiting block 5 and also to store the spring 7 (see reference). Figure 1 and Figure 3 ).

[0030] Furthermore, spring 7 is located inside the sliding groove 9. Spring 7 is in a compressed state and supports the limiting block 5. When compressed, spring 7 can push the limiting block 5 into the groove 6. The rebound strength of spring 7 in the compressed state is greater than the weight of the limiting block 5 (see reference). Figure 1 and Figure 3 ).

[0031] Brief description of usage:

[0032] When using, pull the limit seat 4 away from the control switch of the electric wrench body 1 to make it present a position. Figure 1 In this state, the user's finger can pass between the limit seat 4 and the control switch of the electric wrench body 1 to press the control switch of the electric wrench body 1, thereby controlling the rotation of the rotating head of the electric wrench body 1.

[0033] To prevent the control switch of the electric wrench body 1 from being accidentally activated;

[0034] The user can press the two limit blocks 5 together; when the two limit blocks 5 are pressed, the two limit blocks 5 will separate from the slot 6 and squeeze the two springs 7 respectively, so that they generate a rebound force, and then push the limit seat 4 towards the control switch of the electric wrench body 1. Then, the two limit blocks 5 are released, and the two springs 7 actively rebound and push the two limit blocks 5 to contact the top and bottom of the inner cavity of the support frame 2 respectively. At this time, the limit seat 4 can be pushed normally.

[0035] and Figure 1The spring 3 is in a compressed state. When the limiting block 5 and the slot 6 separate, the limiting block 5 loses its supporting force on the limiting seat 4, and the spring 3 can actively push the limiting seat 4 back to contact the electric wrench body 1.

[0036] At this time, the control switch of the electric wrench body 1 is completely blocked by the limit seat 4, and the control switch of the electric wrench body 1 cannot be pressed, thereby protecting the control switch of the electric wrench body 1 and preventing it from being accidentally touched, which could cause the rotating head of the electric wrench body 1 to rotate and cause danger.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
