New description: [New technical field] This creation is a kind of squatting structure. Here, the piston can be pushed to the bottom by the grip, and the angle can be adjusted with the angle of the grip. The special technique of fixing the piston and the grip is to prevent the grip and the piston from being moved casually when carried. [Prior Art] As shown in Figure 1, the conventional pump is attached to the cylinder (9 work) -~1 u 丄 / J% according to the air-head (92), and the other end is equipped with a cylinder head (93), and a tuyere (92Q) is arranged in the tuyere (92), and a piston (94) is slidably engaged in the cylinder (91), and the piston (94) is connected with a joint (9). 5) 'Connect 5' free end protrudes out of the cylinder head (9 3), and then the outer end of the connecting rod (9 5) is locked with a grip (9 6 ), which can be used by the grip (9 6 ) The connecting rod (9 5 ) drives the piston (9 4) to slide in the cylinder (9 1 ), so that the piston (94) can be controlled to change the volume of the gas inside the gas (91), so that the tuyere (92 (2) can The high pressure gas is sent out; since the piston (9 4) is slid into the cylinder (9 work), the air pump is carried in the vehicle, and the grip (9 6 ) will be easily displaced under the action of external force. The weight will affect the safety of the bicycle. Therefore, when the piston (9 4 ) is at the end, the grip (1) 6 ) can be fitted to the outer periphery of the corresponding end of the cylinder (9 1 ), and in the cylinder (9) 1), grip 5 M329108. Set the (96) facing ring The groove (97) and the protrusion (98) enable the groove (97) and the protrusion (98) to be engaged with each other for axially positioning the piston (9 4 ) and the grip (96). / These structures are quite simple in manufacturing, but there are some inconveniences in operation, specifically: 1. When the groove (97) and the bump (98) are engaged or disengaged from each other, ' It’s quite a big force, and it’s a laborious disadvantage. Lu 2. During the pumping process, when the force on the grip (9 6 ) is excessive or the travel stroke is too large, the groove (9 7 ) and the bump (9 8 ) are easily engaged with each other, and must be carefully controlled. In vain, it is extremely inconvenient to use. The reason is that this creator is concentrating on research and development, and finally uses this creation to improve the use of the pump in the labor and inconvenience. [New Content] The main content of the "Inflator Grip Fixed Structure" is located in the air-to-mouth and gas-red--the counter-reverse seat corresponding to the piston, and the end face of the anti-reverse seat is also used. The block provided by the piston is axially inserted and exited, and the position of the chamber in the surface of the hole is radially provided with a stopper, and the wall of the chamber is provided with a unidirectional rotation of the block at the position of the opposite block. Into the limit slot, the block can be moved into and out of the limit slot by the interlocking force to achieve the axial positioning or release of the piston and the grip.

At this time, by rotating the grip (6 〇) radially, the block (4 3 ) can be driven by the connecting rod (5 〇) and the piston. Corresponding rotation-angle, the block (4 3 ) stop (4 3 2 ) is unidirectionally screwed into the limit groove (76), and during the screwing process, the two stops (432) can It has a slight pressing force and is fixed in the limiting groove (76). At the same time, the stopping portion (4 3 2 ) is axially limited to the weight (7 5 ) β ' so that the grip can be surely prevented (6). 0 The problem of random displacement; the same principle 'only need to reverse the knob (6 〇), that is, the stop (4 3 2 ) of the block (4 3 ) can be released from the limit slot (7 6 And the waiver (7 5) restrictions 'so that the pump can be operated for pumping operation. From the above structural description, the author has at least the following advantages over the conventional use: 1. The creation of the rotating grip (6Q) is controlled Block (43) clutch The strength of the =(76) and the stop (75) is not large, and it is far more labor-saving than the conventional pumping. 2. In the process of pumping, the grip (60) axial movement stroke is too large, Because there is no radial rotation force, the card is not stuck (4 3, 9 M329108 has the problem of locking between the access slot (7 6 ) and the broadcast block (7 5 ), so that the user can quickly operate the pump. Breathing, this creation is full of convenience and convenience. The monthly reading and the seventh, which is the second embodiment of this creation, this embodiment mainly sets the stop (7〇) body to the wind mouth. The end face, • and the rest seat (7〇) can be completely accommodated in the inner hole of the cylinder (10), and the tuyere (20) is provided at the outer diameter of the connecting check seat (70) The larger diameter of the joy (2 2 ), and the thread (2 2 ) (four) has a radially large shoulder (2 6 ), so that the cylinder (10) screw (1 1 ) can be locked to the thread (2 2 ), and the cylinder (10) is pressed against the shoulder (26) to achieve mutual fixation; and the backrest (7 〇) is near the screw # (1 1 ) s position The radial recess is provided with a ring groove (7 2 ), and the outer ring of the 〇-shaped ring (7 3 ) can be adjacent to the inner hole of the cylinder (10) by the 褒 Ο Ο Ο ί ί (7 3 ) button Airtight requirements; the air nozzle head (7 〇) is provided with a chamber (7 4 ) on the outer end surface for axially entering and exiting the block (4 3 ) of the piston, and the chamber (7 4 ) is in the hole The position of the end face of the wall is arranged in the radial direction of the second stop (75). The distance between the two stops (75) and the two parts (4 3 1) of the block (4 3 ) are rotated radially. The hole wall of the chamber (74) is provided with a limit groove (76) for unidirectional screwing of the stop (4 3 2) of the block (4 3 2) at the position of the opposite block (7 5 ); The structure is equivalent to Figure 2. Referring to Figures 8 and 9, which is the third embodiment of the present creation, the embodiment 10 M329108 mainly illustrates that the creation can be applied to a two-stage telescopic pump; it is attached to the cylinder (10). The wind mouth (2 〇) and the wind mouth (2 〇) are equipped with a plug (2 3) and a tuyere (24), while the tuyere (20) and the cylinder (10) are sandwiched with a stop. The seat block is hollow, and is recessed at one end with a chamber (74). The chamber (74) is radially disposed with a stop (75) at the end face of the hole wall, and the chamber ( 7 4) The hole wall is provided with a limit groove (γ 6 ) at the position of the opposite block (7 5 ), and then an inner cylinder (1〇〇) and one end of the inner cylinder (1〇〇) are combined in the cylinder (10). There is a piston that can be airtightly sliding in the cylinder (10), so that the piston C (1 QQ) can be expanded and contracted in the cylinder (J ◦) to link the piston, and the air nozzle (24) is segmented The output of the high-pressure air, and the piston is provided with a block (43) that can axially enter and exit the chamber (74), so that the block (43) can be unidirectionally rotated by the inner cylinder (1 〇 0).
