Be provided with supporting spring between fixed handle and the movable handle.
The below of back pulley is provided with branch.
Preferably, the height of the rear pulley is 1/3 the length of the foreign matter spoon, and after the foreign matter spoon is pulled up, the connection point of the pull rope is equal to the height of the rear pulley.
The stay cord is a metal stay cord.
The beneficial effects of the utility model reside in that:
1. the utility model discloses set up loose pulley assembly, the stay cord is walked around from the front pulley lower extreme, makes the stay cord height reduce, does benefit to the stay cord and walks capable in the steel pipe to pass the steel pipe, be connected with movable handle. Thereby avoid because of the stay cord position is too high, produce the friction with the steel pipe, influence the motion of foreign matter spoon and the foreign matter and take out. The back pulley is close to the foreign matter spoon and sets up, can support the effect that the back pulley played the support when the foreign matter spoon is pulled up, avoids the foreign matter spoon to lean forward. Meanwhile, the foreign matter spoon is connected downwards from the upper part of the rear pulley, so that the foreign matter spoon is easy to pull up due to upward pulling force when being pulled.
2. Set up branch in back pulley below, preceding pulley position is lower, and the stay cord is walked around the top of back pulley, connects in the lower 1/3 department of foreign matter spoon, and back pulley height is about the 1/3 of foreign matter spoon height, ensures that the foreign matter spoon has sufficient area and foreign matter contact, does benefit to outwards to pull out the foreign matter.

Labeled as: 1. fixed handle, 2, movable handle, 3, steel pipe, 4, stay cord, 5, foreign matter spoon, 6, loose pulley assembly, 7, connecting rod, 8, supporting spring, 61, preceding pulley, 62, back pulley, 63, branch.
Detailed Description
In order to illustrate the technical solution of the present invention more clearly and in detail, the present invention is further described below by referring to the following embodiments. The following examples are only for the purpose of specifically illustrating the method of implementing the present invention, and do not limit the scope of the present invention.
Example 1
As shown in fig. 1 and 2, the nasal foreign body forceps convenient to operate comprise a fixed handle 1, a movable handle 2, a steel pipe 3, a pull rope 5, a foreign body spoon 4 and a pulley assembly 6, wherein the upper parts of the fixed handle 1 and the movable handle 2 are hinged, the upper end of the fixed handle 1 is connected with the steel pipe 3, a connecting rod 7 is arranged on the lower side of the tail end of the steel pipe 3, the end part of the connecting rod 7 is hinged with the foreign body spoon 4, the pulley assembly 6 is arranged at a position close to the foreign body spoon 4 by the connecting rod 7, the pulley assembly 6 comprises a front pulley 61 and a rear pulley 62 close to the foreign body spoon 4, one end of the pull rope 5 is connected with the upper end of the movable handle 2, the other end of the pull rope 5 penetrates through the steel pipe 3 and bypasses the front pulley 61 and the rear pulley 62, and the foreign body spoon.
Get the foreign matter, at first hold two handles, draw in two handles in, stay cord 5 is lax, foreign matter spoon 4 is set level, be convenient for place the foreign matter pincers in under the foreign matter, loosen the handle afterwards, make fixed handle 1 keep away from with movable handle 2, stay cord 5 tightens up, can make foreign matter spoon 4 erect at the foreign matter at the back, when the operation apparatus is toward the outer motion, the foreign matter spoon is the outward movement simultaneously, and push the nasal cavity with the foreign matter in its the place ahead forward, be convenient for take out the foreign matter, and can effectively avoid pushing the foreign matter to the nasal cavity deep part, the risk of falling into the air flue even.
Set up front pulley 61 and rear pulley 62, stay cord 5 is walked around from front pulley 61's below, avoids producing the friction because of the stay cord position is too high with the steel pipe, influences the motion and the foreign matter of foreign matter spoon and takes out. The back pulley is close to foreign matter spoon 4 and sets up, can support the effect that plays the support by leaning on back pulley 62 when foreign matter spoon 4 is pulled up, avoids leaning forward. Meanwhile, the foreign matter spoon 4 is connected downwards from the upper part of the rear pulley 62, so that the foreign matter spoon 4 is more easily pulled up by upward pulling force during traction, and the operation is more stable and labor-saving.
Example 2
This example is based on example 1:
as shown in fig. 2, a support spring 8 is provided between the fixed handle 61 and the movable handle 62.
Two handles draw in, and supporting spring 8 compresses, and stay cord 5 relaxes, and foreign matter spoon 4 slowly flattens gradually, sets up supporting spring and is more slowly accurate when being favorable to the operation, is favorable to controlling.
Example 3
This example is based on example 1:
a support rod 63 is arranged below the rear pulley 62.
The height of the rear pulley 62 is 1/3 of the length of the foreign matter spoon 4, and after the foreign matter spoon 4 is pulled up, the connecting point of the pull rope 5 is equal to the height of the rear pulley 62. This high back pulley 62 can support 90 degrees pull-up foreign matter spoon 4 better, and simultaneously, the tie point is established in the lower 1/3 department of foreign matter spoon 4 length to ensure that the foreign matter spoon has sufficient area and foreign matter contact, do benefit to outside pull-out foreign matter, avoided the pulley too big, in the preceding great sheltering from of formation of foreign matter spoon, influence foreign matter spoon and foreign matter contact, thereby influence the foreign matter and take out.
Example 4
This example is based on example 1:
the pull rope 5 is a metal pull rope.
The connection mode not mentioned in the utility model is conventional bonding, threaded connection or integrated into one piece.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention.
