External threads matching the internal threads are arranged on the intermediate quick-release joint. The lower end of the limiting rod is slidably arranged on the support plate. By rotating the support plate, the limiting rod slides obliquely upward along the oblique groove. The quick fixation is realized by the cooperation of the ball and the inclined surface of the pull stud. However, there are still the following defects:

[0003] When the support plate is installed, it is installed by screwing the support plate and the intermediate quick-release joint. The support plate is vertically arranged, and the support plate may move downward under its own gravity, resulting in loose fixation. At the same time, the support plate needs to be continuously screwed during installation, and the installation speed is slow. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1, consisting of Figures 1-5Provided, the present utility model relates to a non-standard tool with an oblique constant pressure fixation with a quick-release joint, including a middle quick-release joint 1. An upper mounting groove 3 is provided at the top of a lower mounting groove 2 opened inside the middle quick-release joint 1. A quick-change tool shank 4 is installed inside the lower mounting groove 2. A pull stud 5 is installed at the top of the quick-change tool shank 4. The bottom wall of the pull stud 5 is inclined. Oblique grooves 6 are equiangularly opened inside the middle quick-release joint 1. The oblique grooves 6 are inclined. One end of the oblique groove 6 penetrates into the upper mounting groove 3. Sliding grooves 7 are symmetrically opened on both sides of the oblique groove 6. A limiting rod 8 is movably installed inside the oblique groove 6. Sliders 9 are symmetrically installed on both sides of the limiting rod 8. The sliders 9 are slidably connected with the sliding grooves 7. A first spring 10 is installed on the side of the slider 9 away from the upper mounting groove 3. A clamping and fixing assembly 11 is installed inside the middle quick-release joint 1. A positioning and limiting assembly 12 is installed outside the middle quick-release joint 1.

[0024] The clamping and fixing assembly 11 includes moving grooves 1101 equiangularly opened inside the middle quick-release joint 1. A side groove 1102 is opened on the side of the moving groove 1101 away from the upper mounting groove 3. The side groove 1102 penetrates to the outside of the middle quick-release joint 1. A clamping plate 1103 is movably installed inside the side groove 1102. A pressure-receiving inclined surface 1104 is provided at the end of the clamping plate 1103. A moving plate 1105 is movably installed inside the moving groove 1101. A connecting rod 1106 is hinged at the bottom end of the moving plate 1105. The other end of the connecting rod 1106 is hinged with the clamping plate 1103. A guide rod 1107 is fixedly installed on the inner top wall of the moving groove 1101. The guide rod 1107 is slidably connected with the moving plate 1105. A second spring 1108 is installed at the top of the moving plate 1105. The top end of the second spring 1108 is fixedly connected with the inner top wall of the moving groove 1101. When the moving plate 1105 moves upward, the clamping plate 1103 is pulled by the connecting rod 1106 to completely enter the side groove 1102. A top block 1109 is fixedly installed at the top of the moving plate 1105. A connecting plate 1110 is provided above the middle quick-release joint 1. The connecting plate 1110 is fixedly connected with the top ends of the respective top blocks 1109.

[0025] The positioning and limiting component 12 includes a support plate 1201 sleeved outside the intermediate quick-release joint 1. Side plates 1202 are equiangularly installed on the outside of the support plate 1201. The side plates 1202 correspond to the clamping plates 1103. An extrusion arc surface 1203 is provided at the top of the side plates 1202. A clamping box 1204 is installed on the side plates 1202. The clamping plate 1103 is inserted into the inside of the clamping box 1204. An extrusion arc surface 1203 is provided at the top of the side plates 1202. When the support plate 1201 moves upward, the extrusion arc surface 1203 acts on the pressure-receiving inclined surface 1104, facilitating the pushing of the clamping plate 1103 into the side groove 1102. When the clamping box 1204 corresponds to the clamping plate 1103, the clamping plate 1103 moves outwards and is inserted into the clamping box 1204, facilitating installation. When the connecting plate 1110 is pulled upward, it can drive each movable plate 1105 to move upward, causing each clamping plate 1103 to be disengaged from the clamping box 1204 simultaneously, facilitating disassembly. A ball is installed at one end of the limiting rod 8 located inside the upper installation groove 3. The ball contacts the inclined bottom wall of the pull stud 5. The bottom end of the limiting rod 8 is set to be hemispherical. The bottom end of the limiting rod 8 contacts the inner wall of the support plate 1201. The first spring 10 is in a stretched state. Clamping boxes 1204 are installed on the side plates 1202 equiangularly installed at the top of the support plate 1201. The clamping plates 1103 provided equiangularly on the intermediate quick-release joint 1 are respectively inserted into the corresponding clamping boxes 1204, enabling the clamping plates 1103 to fix the support plate 1201, and the clamping plates 1103 can provide an upward supporting force for the support plate 1201, preventing the support plate 1201 from moving downward under its own gravity, thereby ensuring the fixing effect of the limiting rod 8 and improving the fixing stability of the quick-change tool shank 4.

[0026] Working principle: During installation, the quick-change tool shank 4 is inserted into the lower installation groove 2, causing the pull stud 5 to enter the upper installation groove 3. Subsequently, the support plate 1201 is sleeved outside the intermediate quick-release joint 1, and the side plates 1202 are made to correspond to the clamping plates 1103 one by one. When the support plate 1201 moves upward, the inner wall of the support plate 1201 is closely attached, pushing the limiting rod 8 towards the inside of the upper installation groove 3, causing the end of the upper installation groove 3 provided with the ball to contact the bottom wall of the pull stud 5, thereby limiting and fixing the lower installation groove 2.

[0027] When the side plate 1202 moves upward, pressure is generated on the pressure-receiving inclined surface 1104 of the clamping plate 1103 by squeezing the arc surface 1203, pushing the clamping plate 1103 into the side groove 1102. During the movement of the clamping plate 1103 towards the inside of the side groove 1102, the movable plate 1105 is pushed upward by the connecting rod 1106, causing the second spring 1108 to be continuously compressed. Then the side plate 1202 continues to move upward. When the clamping box 1204 on the side plate 1202 corresponds to the clamping plate 1103, the clamping plate 1103 moves outward under the elastic force of the second spring 1108 and is clamped into the clamping box 1204 to fix the support plate 1201, thereby positioning the limit rod 8 and fixing the quick-change tool holder 4. When fixing, the support plate 1201 will not loosen under its own gravity, improving the fixing effect on the quick-change tool holder 4. At the same time, each top block 1109 is fixedly connected to the connecting plate 1110. When disassembly is required, only the connecting plate 1110 needs to be pulled upward, thereby pulling each movable plate 1105 upward, and then pulling each clamping plate 1103 to disengage from the clamping box 1204 simultaneously, which is convenient for disassembly and assembly.
