DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] Please refer to Figure 1-5 As shown, the utility model provides a portable teaching power supply, including a teaching power supply 1, two groups of elastic structural members 2 are symmetrically arranged on both sides of the teaching power supply 1, the two ends of the elastic structural member 2 are respectively slidably connected with two groups of first support members 3, the first support members 3 can be limited by a limit block 4, the first support member 3 is connected to the second support member 5 through a driving assembly, the second support member 5 is rotatably connected to the teaching power supply 1, and can be locked by a locking member.

[0023] In this embodiment, the first support member 3 can be pushed out by using an elastic structural member, and at the same time, it can be limited by the limit block 4 to prevent it from detaching. The extended first support member 3 can be used as a handle, and at the same time, it can also provide a certain protection for the side of the teaching power supply 1 in conjunction with the elastic structural member. When the first support member 3 is extended, it can drive the second support member 5 to rotate in conjunction with the driving assembly, so that it can be rotated to the front and rear ends of the teaching power supply 1, which can provide a certain protection for the front and rear ends of the teaching power supply 1. Compared with the prior art, it can be used with a handle for easy carrying, and at the same time, it can provide a certain protection for the teaching power supply 1.

[0024] Please refer to Figure 1-5 As shown, the elastic structural member 2 includes a limit seat 6, a limit rod 7 and a spring 8. A group of limit rods 7 are installed at both ends of the limit seat 6. The limit rods 7 pass through the first support member 3 and are slidably connected thereto. The spring 8 is sleeved on the outside of the limit rod 7. The driving assembly includes a rack 9 and a gear 10. Racks 9 are integrally formed on both sides of the first support member 3. The rack 9 is meshed with the gear 10. The gear 10 is connected to one end of the second support member 5. The locking member is specifically a first fastening bolt 11. The first fastening bolt 11 is threadedly connected to the second support member 5 and can be inserted into the housing of the teaching power supply 1.

[0025] In this embodiment, the first fastening bolt 11 is rotated to disengage it from the housing of the teaching power supply 1, and the lock on the second support member 5 is released. At this time, the elastic force of the spring 8 can push the first support member 3 to slide along the limit rod 7 to extend out of the teaching power supply 1, and at the same time drive the rack 9 to drive the gear 10 to rotate, thereby driving the second support member 5 to rotate. At this time, the first support member 3 extends to both sides of the teaching power supply 1, and the second support member 5 can rotate toward the front and rear ends of the teaching power supply 1. Once the first support member 3 and the second support member 5 are hit, the spring 8 will be compressed. The elastic force generated by the reset of the spring 8 can offset the impact force and provide a certain buffer. It can play a protective role to a certain extent and can also be used as a handle. When the teaching power supply 1 is used, the second support member 5 can be locked by the first fastening bolt 11, so that the first support member 3 and the second support member 5 can be retracted without affecting the use of the teaching power supply 1.

[0026] Please refer to Figure 1-5 As shown, a third support member 12 is installed on the top of the teaching power supply 1. The third support member 12 can be detachably connected to the fourth support member 13 through a second fastening bolt 14. The fourth support member 13 is sleeved on the outside of the teaching power supply 1. The fourth support member 13 is provided with a through groove 15 corresponding to the first support member 3 and the second support member 5.

[0027] In this embodiment, the fourth support member 13 is sleeved on the outside of the teaching power supply 1 to cover the drive components and other components, which can play a protective role and also provide certain protection for the teaching power supply 1. The opening of the through groove 15 will not affect the movement of the first support member 3 and the second support member 5. At the same time, the fourth support member 13 can be connected to the third support member 12 by the second fastening bolt 14, and the fourth support member 14 can be installed and disassembled conveniently.

[0028] Working principle: First, rotate the first fastening bolt 11 to disengage it from the housing of the teaching power supply 1 and release the lock on the second support member 5. At this time, the elastic force of the spring 8 can push the first support member 3 to slide along the limit rod 7 to extend it out of the teaching power supply 1, and at the same time drive the rack 9 to drive the gear 10 to rotate, thereby driving the second support member 5 to rotate. At this time, the first support member 3 extends to both sides of the teaching power supply 1, and the second support member 5 can rotate toward the front and rear ends of the teaching power supply 1. Once the first support member 3 and the second support member 5 are hit, the spring 8 will be compressed. The elastic force generated by the reset of the spring 8 can offset the impact force and provide a certain buffer, which can prevent The teaching power supply 1 can be used as a protective device and can also be used as a handle. When the teaching power supply 1 is used, the second support member 5 can be locked by the first fastening bolt 11, so that the first support member 3 and the second support member 5 can be retracted, which will not affect the use of the teaching power supply 1. The fourth support member 13 is sleeved on the outside of the teaching power supply 1 to cover the drive components and other components, which can play a protective role and also provide certain protection for the teaching power supply 1. The opening of the through groove 15 will not affect the movement of the first support member 3 and the second support member 5. At the same time, the fourth support member 13 can be connected to the third support member 12 by the second fastening bolt 14, and the fourth support member 14 can be installed and disassembled easily.
