Furthermore, in order to prevent the movable seat from being accidentally impacted and slid, the air-spinning retracting shaft is taken out of the receiving seat, wherein the movable seat and the fixed seat are respectively provided with a positioning groove M443093 and a positioning block, when the positioning groove and the positioning block are mutually When the alignment is made, the movable seat can be pushed backwards, so that the inflation roll retracting shaft can accommodate or take out the receiving seat. However, when the drive shaft is stopped, there is also a certain probability that the positioning groove and the positioning block are aligned with each other. In addition, after the inflation coil retracts the shaft before the winding receiving member, a slight amount of flexural deformation occurs due to the change in the weight of the material, which causes the pressing force to move the movable seat to the positioning holder. Therefore, the creators further actively develop and improve to provide a safer structure with a safety structure and a retractable shaft drive positioning clamp. [New content] Comprehensively, the shortcomings of the prior art, including the conventional air-slewing reel drive positioning clamp, have a safety design to prevent accidental disengagement, but there is still the possibility of disengagement at a certain probability. In view of the above-mentioned shortcomings, the present invention proposes a scheme of a pneumatically swellable retracting shaft driving positioning clamp with a safety structure, which can be used after the air-expansion retracting shaft drives the positioning clamp seat, after the safety structure is activated by the user. In order to take out the inflation roll retraction shaft to ensure work safety. The present invention is a pneumatic expansion retracting shaft driving positioning clamp with a safety structure, the positioning clamping seat includes a driving shaft, one end of the driving shaft is coupled to a power source, and a locking mechanism is disposed thereon. And a bearing seat, and the driving shaft is disposed at the other end of the power source and is provided with a receiving groove for receiving an inflation end of the shaft, and driving the driving by the power source The shaft can drive the inflation roll to rotate, wherein: the drive shaft is adjacent to the locking seat and is provided with at least one elastic key, the elastic key can be elastically protruded from the surface of the drive shaft for making The driving shaft and the locking base M443093 are engaged with each other, and a safety bolt is correspondingly arranged at the locking seat, and the end of the safety bolt can resist the surface of the elastic key. The main purpose of the creation is that when the user presses the safety bolt, the pressing elastic key can be retracted into the surface of the driving shaft, so that the driving shaft and the locking seat can be separated from each other, so that the locking seat can be driven along The shaft is slid forward and backward to take out or put the end of the air-spinning shaft into the slot. The secondary purpose of the present invention is that a locking groove is recessed in the direction of the bearing seat, and the bearing seat is provided with a positioning block on one side of the positioning groove, when the positioning groove is opposite to the positioning block. The lock seat is displaced in the direction of the bearing housing to form a second safety device. Another purpose of the creation is that the elastic key and the safety bolt can be arranged in a single set on the positioning clamp, or in two sets on the opposite side, to increase the fixing ability of the elastic key and prevent the escape. Security effect. [Embodiment] For the convenience of the description of the central idea expressed in the column of the above novel content, it is expressed by a specific embodiment. The various items in the embodiments are depicted in terms of ratios, dimensions, amounts of deformation, or displacements that are suitable for illustration, and are not drawn to the proportions of actual components, as set forth above. In the following description, like elements are denoted by the same reference numerals. Referring to the first to fourth figures, the present invention is an air-spinning retracting drive positioning clamp with a safety structure, the positioning clamp includes: a driving shaft 10, the driving shaft 10 One end is coupled to a power source 90, and the drive shaft 10 is disposed at the other end of the power source 90 and is provided with a M443093 accommodating groove 11 for accommodating an end of the inflation shaft 91 The driving shaft 10 is driven by the power source 90 to drive the inflation coiling shaft 91 to rotate. a locking seat 20 is provided with a shaft hole 21 through which the driving shaft 10 can be inserted, and the locking seat 20 can be displaced in the axial direction of the driving shaft 10 to selectively lock the shaft The seat 20 is closed at the opening of the accommodating groove 11. A bearing block 30 is disposed on the drive shaft 10, and at least one bearing 31 is disposed between the bearing base 30 and the drive shaft 10 to enable the drive shaft 10 to smoothly rotate in the bearing housing 30. The drive shaft 10 can be positioned at the machine table by the bearing housing 30. A safety structure 40 is disposed on the drive shaft 10 adjacent to the locking seat 20 and is provided with at least one elastic key 41. The elastic key 41 is elastically protruded from the surface of the drive shaft 10 for the drive shaft 10 to The locking bases 20 are engaged with each other. For example, the driving shaft 10 is adjacent to the locking base 20, and at least one elastic groove 42 for receiving the elastic key 41 is recessed, and the elastic key 41 and the elastic groove 42 is provided with an elastic member 43, which can be a spring piece. A recessed groove 44 is formed in the side wall surface of the shaft hole 21 of the locking seat 20 for engaging the elastic key 41. A safety bolt 45 is disposed at the locking seat 20, and the end of the safety bolt 45 is in contact with the surface of the elastic key 41, and is retracted into the elastic groove 42 by the movable pressing elastic key 41. For example, the radial direction of the locking seat 20 is provided with at least one radial hole 46 for receiving the safety bolt 45, and one end of the radial hole 46 is connected to the insertion groove 44. The M443093 full bolt 45 has a pressing end 47 exposed to the outer periphery of the locking seat 20, and a spring 48 is disposed between the pressing end 47 and the radial hole 46. Further, as shown in the third figure, the locking seat 20 is recessed with respect to the direction of the bearing housing 30 to define a positioning groove 22, and the bearing housing 30 is provided with a positioning block 32 on one side of the positioning groove 22. When the positioning slot 22 is opposite to the positioning block 32, the positioning block 32 can be received in the positioning slot 22 to create a movable space for the displacement of the locking seat 20 in the direction of the conventional bearing housing 30. If the positioning groove 22 is not aligned with the positioning block 32, the locking block 20 cannot be prevented from slipping because the positioning block 32 abuts against the side of the locking seat 20. After clarifying the detailed structure of the above case, the following is a detailed explanation of the action of the case:: As shown in the third figure, when the user wants to perform the disassembly and assembly of the inflation roll retracting shaft 91, the power source 90 is stopped first. Rotating to keep the drive shaft 10 in a stationary state, the drive shaft 10 is finely adjusted by hand or tool to a position where the positioning φ groove 22 is opposed to the positioning block 32. As shown in the fourth figure, when the safety pin 45 is not pressed, the elastic key 41 is biased by the elastic force of the elastic member 43 to block between the elastic groove 42 of the drive shaft 10 and the recess 44 in the locking seat 20. The displacement of the lock base 20 on the drive shaft 10 can be prevented. At this time, as shown in the fifth figure, the user presses the safety pin 45 to retract the elastic key 41 to the surface of the drive shaft 10, and separate the elastic key 41 from the slot 44, thereby enabling the locking seat 20 to be along The drive shaft 10 is axially slipped. In addition, when the positioning slot 22 is opposite to the positioning block 32, as the locking M443093 seat 20 axially slides, the positioning block 32 can enter the positioning slot 22 (as shown in FIG. 6), so that the locking seat 20 is obtained. In the past, the bearing housing 30 is displaced enough to expose the opening of the receiving slot 11 so that the user can take out or put the end of the inflation coiling shaft 91 into the slot 11 (as shown in FIG. 7). Furthermore, in the installation, only the reverse operation is required, so that the opening of the accommodating groove 11 is re-closed by the locking seat 20, and the elastic key 41 is re-engaged in the recessed groove 44, and the installation operation can be completed. The end of the expanding and retracting shaft 91 is fixed in the accommodating groove 11. This creation ensures that the locking seat 20 can be slipped on the drive shaft 10 by the arrangement of the resilient keys 41. In use, only the safety bolt 45 is pressed, and the elastic key 41 can be retracted into the surface of the drive shaft 10, so that the drive shaft 10 and the locking seat 20 are movably separated, so that the locking seat 20 can be along the drive shaft 10 The front and rear slides are performed to take out or put the end of the inflation roll retracting shaft 91 into the self-receiving groove 11. When the inflation coil retracting shaft 91 is before the winding receiving member, a slight deformation occurs due to the change of the weight of the material, which causes the pressing force to be applied to the positioning central seat to push the locking seat 20, due to the elastic key 41 and the groove 44 The snap-in positioning effect prevents the positioning clip from being pressed and pushed by the inflation roll retracting shaft 91 to increase safety. And the elastic key 41 and the safety bolt 45 and the like may be arranged in a single set at a single side position on the positioning clamp seat or in two sets on the opposite side according to the requirements of the operation of the machine to increase the fixing of the elastic key 41. Ability and safety against detachment. M44JQ93 Furthermore, the positioning groove 22 and the positioning block 32 2 can only be used for the safety of the positioning groove 22 and the positioning block 32. 15 俾 Shape---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- And this creation is extremely important, Mai has filed a patent application, and has actually paid for the patent approval.
