Referring to fig. 1-6, the present embodiment provides an adjustable socket wrench, which includes a handle 1, a ratchet 2 and a sliding barrel 3 are disposed on the handle 1, and a clamping member for clamping a screw is disposed on the sliding barrel 3. In this scheme, joint spare is sleeve 4, and handle 1 is provided with the cavity, and the cavity embeds there is ratchet 2, be provided with the through-hole on the ratchet 2, smooth section of thick bamboo 3 in but the relative slip setting of ratchet 2 in the through-hole, and be provided with first spacing subassembly 5 on the ratchet 2, smooth section of thick bamboo 3 for when ratchet 2 slides the assigned position, ratchet 2 passes through with smooth section of thick bamboo 3 first spacing subassembly 5 fixed connection.

When a nut or a screw to be disassembled by a knob is in a counter bore or the counter bore is deep, a sleeve 4 of the ratchet 2 wrench is blocked outside a hole due to a wrench handle or a barrier is arranged beside the nut or the screw to be disassembled by the knob, so that the disassembly or assembly action cannot be realized. For example, when a nut to be loosened on a knob angle is needed, the ratchet 2 wrench is likely to interfere with a steel plate on one side of the angle during rotation, and is difficult to detach. In the scheme, the relative position of the sliding cylinder 3 and the ratchet wheel 2 is changed by sliding the sliding cylinder 3. And because the joint spare sets up on smooth cylinder 3, and ratchet 2 sets up on hand, and at the in-process that smooth cylinder 3 and ratchet 2 slided relatively, the interval of joint spare and handle 1 has also changed, as long as adjust smooth cylinder 3 until sleeve 4 and hand the interval satisfy under the condition of the degree of depth of counter bore or the height of barrier, and then avoided the problem of the action that can't realize dismantling or install. After the position of the ratchet wheel 2 is selected, the pawl in the wrench handle can be shifted to a required direction according to different directions during disassembly or assembly.

And a pawl for stirring the ratchet 2 to rotate is arranged in the handle 1, and the pawl is reversed by a set of marbles, springs and a plug screw. When the pawl is put into the groove of the ratchet 2, the tail part of the handle 1 is held by hand, and the spanner handle 1 is shaken back and forth left and right, so that the nut can be disassembled or assembled. At the moment, the ratchet 2 is driven by the pawl, the ratchet 2 drives the sliding barrel 3, the sliding barrel 3 drives the sleeve 4, and the sleeve 4 drives the nut, so that the force is transmitted to the nut from the wrench handle, and the purpose of dismounting or mounting is achieved.

As a specific embodiment, the first limiting component 5 comprises an ejector pin 52 and a compression spring 51, the outer wall of the ratchet 2 is provided with a first through groove 21, and the first through groove 21 is communicated with the through hole. Meanwhile, the ejector pin 52 and the compression spring 51 are both arranged in the groove of the first through groove 21. Specifically, the compression spring 51 is wound around the outer wall of the knock pin 52, one end of the compression spring 51 is connected to the groove wall of the first through groove 21, and the other end of the compression spring 51 is connected to the knock pin 52. The outer wall of the sliding cylinder 3 is provided with a plurality of grooves along the length direction of the sleeve 4, and the pressure spring 51 can drive the ejector pin 52 to reset and insert into the groove of any groove. When the relative position of the sliding cylinder 3 and the ratchet 2 needs to be adjusted, the ejector pin 52 is pulled firstly, the ejector pin 52 extends out of the groove, the pressure spring 51 is stretched, and the locking of the sliding cylinder 3 and the ratchet 2 is released. Then the sliding barrel 3 is pulled to a designated position, so that the distance between the clamping piece and the ratchet 2 is changed along with the change of the sliding barrel 3. When the sliding barrel 3 is adjusted until the distance between the clamping piece and the handle meets the depth of the counter bore or the height of the barrier, the nearest groove is aligned with the first through groove 21, the ejector pin 52 is loosened, and the pressure spring 51 contracts to drive the return to be inserted into the groove of the groove, so that the sliding barrel 3 and the ratchet wheel 2 are fixed. Meanwhile, the ejector pin 52 and the groove between the ratchet wheel 2 and the sliding barrel 3 are matched with the key groove, so that sliding and force transmission are realized, and the problem that the ratchet wheel 2 cannot drive the sliding barrel 3 to rotate is solved.

In this scheme, the quantity of sleeve 4 is a plurality of, is provided with the first passageway 42 that is used for joint screw in every sleeve 4, and first passageway 42 sets up along the length direction of sleeve 4. And the first channels 42 of the plurality of sleeves 4 have different sizes, and each sleeve 4 can be detachably connected with the sliding barrel 3. It is easy to understand that the nuts or screws on different disassembly points or mounting points have different sizes, and only one sleeve 4 is adopted, so that if the nuts or screws on the disassembly points or the mounting points are too large or too small, the problem that the nuts or screws cannot be disassembled or mounted can occur. In the scheme, each sleeve 4 can be detachably connected with the sliding barrel 3, and the first channels 42 of the sleeves 4 are different in size. According to the size of the nut or screw on the disassembly point or the assembly point, the corresponding sleeve 4 is selected to be fixed on the sliding barrel 3, so that the device can disassemble or assemble the screw or nut with different sizes.

In order to achieve a detachable connection of the sleeve 4 to the slide 3. In the scheme, the sliding cylinder 3 is sleeved in the channel of the first channel 42, the outer wall of the sleeve 4 is provided with a second through groove 41, a jacking pin 52 and a pressure spring 51 are arranged in the second through groove 41, one end of the pressure spring 51 is connected with the groove wall of the second through groove 41, the other end of the pressure spring 51 is connected with the jacking pin 52, and the second through groove 41 is communicated with the first channel 42 of the sleeve 4. The outer wall of the sliding cylinder 3 is provided with a positioning groove, and the pressure spring 51 can drive the ejector pin 52 to reset and insert into the groove of the positioning groove.

Meanwhile, in order to keep the connection between the slide cartridge 3 and the sleeve 4 stable, the slide cartridge 3 is provided with a socket part 32 for being socket-connected in the first channel 42, and the cross section of the socket part perpendicular to the axis of the slide cartridge 3 is a polygonal structure. When the sleeve joint part 32 is sleeve jointed with the first channel 42, the inner wall of the first channel 42 is jointed with the outer wall of the sleeve joint part 32, namely the cross section of the first channel 42, which is vertical to the axis of the slide cylinder 3, is also in a polygonal structure. Thereby ensuring the connection stability and the reliability of the slide cylinder 3 and the sleeve 4 under stress. Specifically, the sleeve connecting portion 32 in this embodiment has an octagonal structure, but it is easy to understand that the connection stability and the reliability when the force is applied to the spool 3 and the sleeve 4 are ensured, and the specific shape is not limited.

In addition, a second channel 31 is arranged in the sliding barrel 3, the second channel 31 penetrates through two ends of the sliding barrel 3 along the length direction of the sliding barrel 3, and when the sleeve 4 is sleeved on the outer wall of the sliding barrel 3, the first channel 42 is communicated with the second channel 31 to form a bolt channel for passing through a bolt. In practical use, it is found that the bolt on the iron tower (containing the metal accessories and the like) is often much higher than the nut, so that the existing ratchet 2 wrench cannot sleeve the sleeve 4 on the nut. The ratchet 2 and the common sleeve 4 are made into a hollow structure through the second passage 42 and the first passage 31, and the sleeve 4 can be sleeved on the nut no matter how much the bolt is higher than the nut.
