Description

Technical Field

[0001] The invention relates to the field of permanent magnets, in particular to a side-loading and replaceable bit type screwdriver with a built-in permanent magnet. Background Art

[0002] The screwdriver is a very commonly used tool. Nowadays, screwdrivers can easily replace various blade heads, from flat-blade to cross-blade, and even hexagonal and hexagonal blades. The general way to replace the blade head of a screwdriver is to replace it from the front end through the magnetic suction principle. However, as the magnetic suction force gradually weakens, this design will eventually lead to the scrapping of the screwdriver function, and the blade head is very easy to lose. If rear or side replacement parts are used, this problem can be solved. Summary of the invention

[0003] The main technical problem solved by the present invention is to provide a side-loading replaceable bit type screwdriver with a built-in permanent magnet, which can very conveniently replace the bit of the screwdriver and is not easy to be lost.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: to provide a side-loading and replaceable bit type screwdriver with a built-in permanent magnet, comprising a screwdriver handle and a connecting head, the front end of the screwdriver handle is connected to the connecting head, the front end surface of the connecting head is inwardly recessed to provide a regular hexagonal clamping groove, a hollow pipe is provided inside the screwdriver handle, one end of the hollow pipe is connected to the rear end of the clamping groove, the rear end opening of the clamping groove is larger than the front end opening of the clamping groove, a loading port is provided on the side wall of the screwdriver handle, the lower end of the loading port is connected to the hollow pipe, the rear end of the hollow pipe is connected to a circular rare earth neodymium magnet, the upper end surface of the rare earth neodymium magnet is an N pole or an S pole, the side end of the rare earth neodymium magnet is connected to a flip shaft, one end of the flip shaft is led out of the side wall of the screwdriver handle, storage grooves are provided on both sides of the rear end of the screwdriver handle, several types of replacement bits are provided inside the storage grooves, and the bottom end of the replacement bits is connected to a permanent magnet.

[0005] In a preferred embodiment of the present invention, the bottom end surface of the permanent magnet is an N pole or an S pole.

[0006] In a preferred embodiment of the present invention, one end of the flip shaft is connected to a paddle.

[0007] In a preferred embodiment of the present invention, the front end diameter of the replacement cutter head is larger than the opening diameter of the positioning slot.

[0008] The beneficial effect of the present invention is that the present invention designs a screwdriver capable of replacing the screwdriver head at the side end, and the process of replacing the screwdriver head is just like replacing a single piece of a pistol. The screwdriver head enters the internal pipe from the side, and is moved forward to the front end bayonet by the repulsive force generated by the internal rear end magnetic steel. The reverse operation is to suck back the screwdriver head, and it only requires changing the magnetic poles of the magnetic steel, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 , the embodiment of the present invention includes:

[0014] A side-loading and replaceable bit screwdriver with a built-in permanent magnet comprises a screwdriver handle 1 and a connector 2, wherein the front end of the screwdriver handle 1 is connected to the connector 2, and the front end surface of the connector 2 is inwardly recessed to form a regular hexagonal positioning groove 3, and a hollow pipe 4 is provided inside the screwdriver handle 1, and one end of the hollow pipe 4 is connected to the rear end of the positioning groove 3, and the rear end opening of the positioning groove 3 is larger than the front end opening of the positioning groove 3, and a mounting hole is provided on the side wall of the screwdriver handle 1. A filling port 5, the lower end of which is connected to the hollow pipe 4, the rear end of which is connected to a circular rare earth neodymium magnet 6, the upper end surface of which is an N pole or an S pole, the side end of which is connected to a flip shaft 7, one end of which is led out of the side wall of the screwdriver handle 1, storage grooves 8 are arranged on both sides of the rear end of the screwdriver handle 1, several types of replacement tool heads 9 are arranged inside the storage grooves 8, and the bottom end of the replacement tool head 9 is connected to a permanent magnet 10.

[0015] In addition, the bottom end surface of the permanent magnet 10 is an N pole or an S pole.

[0016] In addition, one end of the flip shaft 7 is connected to the shifting piece.

[0017] In addition, the front end diameter of the replacement cutter head 9 is larger than the opening diameter of the positioning slot 3 .

[0018] The working principle of the present invention is that the front end of the screwdriver handle 1 is connected to the connecting head 2, the front end surface of the connecting head 2 is recessed inward to provide a regular hexagonal clamping groove 3, the interior of the screwdriver handle 1 is provided with a hollow pipe 4, and one end of the hollow pipe 4 is connected to the rear end of the clamping groove 3.

[0019] The rear end opening of the positioning slot 3 is larger than the front end opening of the positioning slot 3. A loading port 5 is opened on the side wall of the screwdriver handle 1. The lower end of the loading port 5 is connected to the hollow pipe 4. The rear end of the hollow pipe 4 is connected to a circular rare earth neodymium magnet 6. The upper end surface of the rare earth neodymium magnet 6 is an N pole or an S pole. The magnet has a very strong suction or thrust and has a very strong magnetic energy.
