Technical Field

[0001] This utility model relates to the field of screwdriver technology, specifically a screwdriver with an anti-slip structure. Background Technology

[0002] A screwdriver is a common tool used to tighten screws into place. It usually has a thin wedge-shaped head that can be inserted into the slot or notch of the screw head. There are two main types: flathead (minus sign) and Phillips head (positive sign). There are also common hex screwdrivers, including internal hex and external hex screwdrivers.

[0003] According to Chinese patent CN2238710Y, this utility model relates to a screwdriver with an anti-slip sleeve, including a screwdriver blade and a handle. Its key feature is that an anti-slip sleeve is tightly fitted over the handle. Using this screwdriver increases the force output, reduces slippage, prevents blisters on the hands, improves work efficiency, and protects workers.

[0004] Existing screwdrivers may simply use a non-slip handle to increase friction and prevent slippage during screw tightening. While this design can improve the anti-slip performance to some extent, the non-slip handle may wear down after prolonged use. This makes the screwdriver uncomfortable to hold, potentially hindering screw tightening and causing wear on the screw tip, ultimately preventing the screw from being unscrewed.

[0005] Therefore, a screwdriver with an anti-slip structure is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technology and solve the problem that the anti-slip handle may become damaged after prolonged use, resulting in an uncomfortable grip when using the screwdriver and difficulty in effectively turning the screw, causing wear on the screw tip and making it impossible to unscrew the screw smoothly.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The screwdriver with anti-slip structure of this utility model includes a screwdriver body, an anti-slip control component connected to the top of the screwdriver body, a screwdriver tip replacement component provided at the bottom of the screwdriver body, and a force-applying rod engaged inside the screwdriver body; the anti-slip control component includes an anti-slip sleeve, a protective protrusion integrally provided on the outer wall of the anti-slip sleeve, a locking block fixedly connected inside the anti-slip sleeve, a connecting seat provided on the top of the anti-slip sleeve, a slot provided on the outer wall of the connecting seat, a limiting cover provided on the top of the connecting seat, a protrusion fixedly connected inside the limiting cover, an elastic plate connected to the top of the protrusion, and a first spring installed on the top of the elastic plate.

[0008] Preferably, the protective protrusions are set at equal angles to the outer wall of the anti-slip sleeve, and both the anti-slip sleeve and the protective protrusions are made of silicone. The anti-slip sleeve also forms a locking structure with the screwdriver body through a locking block.

[0009] Preferably, the limiting cover is detachable through a protrusion, a slot and a connecting seat, and the elastic plate is elastic through a first spring and a protrusion.

[0010] Preferably, the cutter head replacement assembly includes a cutter head body, a control plate is connected to the outer wall of the cutter head body, a second spring is installed inside the control plate, and a limit block is fixedly connected to the outer wall of the control plate.

[0011] Preferably, the cutter head body is detachable from the screwdriver body via a limiting block, and the cutter head body and the screwdriver body are engaged. The limiting block is elastically connected to the cutter head body via a control plate and a second spring.

[0012] Preferably, the force-applying rod and the screwdriver body form a locking structure, and the force-applying rod and the screwdriver body are arranged perpendicularly.

[0013] The advantages of this utility model are:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1 to 3As shown, a screwdriver with an anti-slip structure includes a screwdriver body 1, an anti-slip control component 2 connected to the top of the screwdriver body 1, and a screwdriver tip replacement component 3 provided at the bottom of the screwdriver body 1. An extension rod 4 is also internally engaged with the screwdriver body 1. The anti-slip control component 2 includes an anti-slip sleeve 201, protective protrusions 202, a locking block 203, a connecting seat 204, a slot 205, a limiting cover 206, a protrusion 207, an elastic plate 208, and a first spring 209. The anti-slip control component 2 can increase the anti-slip performance of the screwdriver through the anti-slip sleeve 201, and facilitates replacement when the anti-slip sleeve 201 becomes worn. The protective protrusions 202 are set at equal angles to the outer wall of the anti-slip sleeve 201, and the anti-slip sleeve 201... 01. The protective protrusions 202 are all made of silicone. The anti-slip sleeve 201 forms a locking structure with the screwdriver body 1 through the locking block 203. The limiting cover 206 forms a detachable structure with the protrusion 207, the slot 205 and the connecting seat 204. The elastic plate 208 forms an elastic structure with the protrusion 207 through the first spring 209. The silicone anti-slip sleeve 201 and protective protrusions 202 can increase the anti-slip performance of the screwdriver and prevent wear on the screw end during screw tightening. At the same time, the anti-slip sleeve 201 can be removed and replaced after the limiting cover 206 is removed. It can also prevent the anti-slip sleeve 201 and the screwdriver body 1 from rotating during screw tightening. It is simple to operate and easy to use.

[0026] like Figure 1 and Figure 4 As shown, a screwdriver with an anti-slip structure includes a screwdriver tip replacement assembly 3, comprising a screwdriver tip body 301, a control plate 302, a second spring 303, and a limiting block 304. The screwdriver tip replacement assembly 3 allows for the replacement of a suitable screwdriver tip with a notch at the end of the screw, facilitating better screw removal. The screwdriver tip body 301 is detachable from the screwdriver body 1 via the limiting block 304, and the screwdriver tip body 301 and the screwdriver body 1 form a locking structure. The limiting block 304, through the control plate 302 and the second spring 303, forms an elastic structure with the screwdriver tip body 301. After the screwdriver tip body 301 is locked in the screwdriver body 1, the four sets of limiting blocks 304 can lock the screwdriver tip body 301 in place, effectively preventing the screwdriver tip body 301 from falling out of the screwdriver body 1. Furthermore, the screwdriver tip body 301 can be disassembled by pressing the four sets of control plates 302. The corresponding screwdriver tip body 301 can be replaced according to the shape of the screw end, increasing the practicality of the device.

[0027] like Figure 1 and Figure 2As shown, a screwdriver with an anti-slip structure has a lever 4 and a screwdriver body 1 forming a locking structure, and the lever 4 and the screwdriver body 1 are set perpendicularly. By inserting the lever 4 into the screwdriver body 1, when encountering a screw that is difficult to turn, the operator can rotate the lever 4 with the other hand, thereby increasing the torque and making the screw easier to unscrew.

[0028] Working principle: First, press the four control plates 302. At this time, the control plates 302 will squeeze the second spring 303, thereby causing the limiting block 304 to move outward of the screwdriver body 1, thus separating from the head body 301. At this time, the head body 301 can be disassembled, and a suitable head body 301 can be replaced according to the shape of the groove at the end of the screw. After the replaced head body 301 is inserted into the screwdriver body 1, the square block on the top of the head body 301 will engage with the screwdriver body 1, so that the screwdriver body 1 and the head body 301 can rotate synchronously. Release the control plates 302. At this time, under the action of the elastic force of the control plates 302 and the second spring 303, the limiting block 304 will be pushed towards the head body 301, thereby fixing the head body 301 inside the screwdriver body 1 and preventing the head body 301 from falling off.

[0029] Next, the operator holds the anti-slip sleeve 201 and inserts the screwdriver body 301 into the groove at the end of the screw. Applying pressure will loosen the screw. If the screw is too tight, the lever 4 is inserted into the screwdriver body 1. The operator can then press down on the screwdriver body 1 with one hand and rotate the lever 4 with the other, providing greater torque. If the anti-slip sleeve 201 wears down after prolonged use of the screwdriver body 1, the operator presses down and rotates the limiting cover 206 to disengage the protrusion 207 from the slot 205, allowing the limiting cover 206 to be removed from the connecting seat 204. The anti-slip sleeve 201 can then be removed from the screwdriver. When replacing the anti-slip sleeve 201 on the main body 1, align the locking block 203 inside the anti-slip sleeve 201 with the notch on the screwdriver main body 1 and push the anti-slip sleeve 201 into it. At this time, align the protrusion 207 inside the limiting cover 206 with the slot 205 on the outer wall of the connecting seat 204 and press the limiting cover 206 down so that the protrusion 207 is engaged inside the slot 205. At this time, under the action of the elastic force of the first spring 209, the elastic plate 208 can be pushed and pressed against the end of the connecting seat 204, thereby increasing the friction and preventing the limiting cover 206 from falling off the connecting seat 204.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
