New description: [New technology field] This creation department is related to butter grabbing, especially about the improved structure of a double-buckle butter. [Prior Art] In the patent publication No. 2009/0272762A1, a specific technical content of a two-stroke butter grab is disclosed. In general, the technical content provided by the patent disclosure is as follows. The spurs are simultaneously and separately in the flow passages of different sizes and inner diameters, and the reciprocating piston rudder motion is used to push the butter in the flow passage, and the large inner diameter flow passage can push a large amount of butter flow through the spurs. A low-pressure, high-flow, butter-pushing state is achieved, and a low-pressure, small-wave, butter-pushing state is simultaneously provided by a small-diameter flow path. In this way, when the butter is used for the two-stroke grease gun, the same side of each of the ratchet cups can be passed through, and the butter is largely reduced to the desired fine position, and during the push of the oil. The butter grab will be counter-pressed by the butter note (4). As a result, when the pressure is too high, the operator will only use the manpower to make the butter stick out of the butter.

The fifth drawing is a cross-sectional view of a preferred embodiment of the present invention along the secant line of the first figure b-b, wherein the push-and-push operation of the first push-pushing portion is the result of the reflow. Figure 6 is a schematic cross-sectional view of another preferred embodiment of the present invention in which the normally closed valve is locked without functioning. Fig. 7 is a schematic cross-sectional view showing another preferred embodiment of the present invention, wherein the normally closed valve is released and can be subjected to external force to change its usual state. First, please refer to the first to fifth figures. In the preferred embodiment of the present invention, the improved structure (10) of the double-spindle butter is provided, which is mainly composed of a part (20) and a tube. The body (30), a first feeding portion (40), a second feeding portion (50) and a drainage portion (60), wherein: the seat portion (20) has a body (21), one into The flow end (211) and one outflow end (212) are respectively located on the opposite ends of the body (21), and a column bushing (22) is embedded in the body (21), 5 M391608 * « • The first and second inlet ports (23) (24) extend inwardly from the inlet end (211) into the bushing (22), and a rocker arm (25) is pivotally mounted to the body (25) 21) On. The barrel (30) is a tubular container for containing a semi-fluid such as butter, and is connected to the inlet end (211) of the seat with an open end, and the inside of the barrel (3) The space is connected to each of the inlets (23) (24). The first feeding portion (40) has a first flow passage (41) disposed on the bushing (22) and is associated with the first inlet The flow port (23) is connected, and a first ratchet rod (42) is axially disposed at one end of the shaft shaft in the first flow passage (41) and is axially biased by a user via the rocker arm (25). The reciprocating piston movement is performed to push the semi-fluid located in the first flow path (41) to flow outward from the outflow end (212). The second feeding portion (50) has a second flow path (51) having a smaller inner diameter than the first flow path (41), and is disposed on the bushing (22) and the first flow path ( 41) parallelly communicating with the second inlet port (24), a second ratchet rod (52) is coaxially slidably disposed at one end in the second flow passage (51), and the first ratchet rod (42) is simultaneously driven by the rocker arm (25) to push the semi-fluid located in the second flow path (51) outwardly from the outflow end (212). φ However, with regard to the specific technical content of each of the first and second feeding units (40) (50), the applicant considers that it is a standard of the prior art, and is no longer redundant here. The drain portion (60) has an inner annular channel (61) interposed between the circumferential side of the bushing (22) and the body (21), and each of the first and second intake ports (23) (24) is connected to each other, and a splitter hole (62) extends inwardly from one side of the body (21) to be in vertical communication with the first flow path (41) for communicating the first flow path (41) And a channel (61), a normally closed valve (63) is disposed in the branching hole (62) for blocking communication between the first flow path (41) and the channel (61); Further, the normally closed valve (63) is composed of a resist body (631), an elastic body (632) and a M391608. The end body (633) is sequentially accommodated in the shunt hole (62). The resist (631) is in the shape of a bead and is rollable in the shunt hole (62), and is reciprocally displaced between an open and a closed position, when the resist (631) is located at the blocking In the position, the orifice of the branching hole (62) communicating with the first channel (3) is closed, and when located in the open position, the first channel (41) and the channel (61) are closed. The connection between the holes (62) is unobstructed; the end body (633) is a bolt that is screwed into the The orifice (62) is located in the orifice of the outer end surface of the body (5); the φ-transducing body (632) is a compression bomb, which is lost between the end body (633) and the resistor body (631), and it The resisting body (631) is elastically held in the blocking position. With the composition of the above-mentioned components, please refer to the second and third figures, the improved structure (10) of the double-spindle butter is used for the operator to operate in the traditional way, that is, the shake The arm (25) drives each of the ratchet rods (42) (52) to reciprocally displace, so that half of the fluid in each of the flow passages (9) (8) is sent out from the outlet end (212) of the body (21) to the application target. When the reaction force generated by the application of the target (or the back house) causes the operator to apply the force on the first ratchet φ 42 (42) which forms a large flow rate less than the back pressure, please refer to the fourth figure. As shown in the fifth figure, at this time, the semi-fluid cannot be pushed from the first flow path (41) to the outflow end (212), and thus the force exerted by the operator pushes the first flow path (41). When the inner semi-fluid flows, the resist body (631) will be pushed up, and the shunt hole (62) will be unobstructed, and flow into the channel (61) and flow back to the first inlet port (23). Therefore, the first ratchet rod (42) is also subjected to reciprocating motion even when the back pressure is very large, so as to avoid obstructing the sending of the second ratchet rod (52) for forming a high pressure and a low flow rate. Material operation. In summary, the improved structure of the ratchet butter (1〇) is the same as the conventional technology in the way of use, and the same feeding effect is achieved, but the improved structure of the double-buckle butter is adopted. The specific technical content of the M391608 (10), through the structural design of the internal channel (61), is relatively simpler than the conventional technology, and can reduce the manufacturing cost, so that the end body (633) is presented The exposed design 'further allows the user to adjust the preset elastic force provided by the elastic body (632) to the resisting body (631) according to the state of use, so as to flexibly respond to the needs of use. Referring again to the sixth and seventh figures, the modified structure (10) of the double-spindle butter squirt provided in another preferred embodiment of the present invention is substantially the same as that disclosed in the foregoing embodiment. The difference is only in the end body (the difference in the structure of 633 ') Specifically, the end body (633) provided in this embodiment is a cam that is disposed in the shunt hole and makes the pivot The axial direction is perpendicular to the diversion hole (the hole axis of the 62〇 is used to make the end body (633) rotate between a locking and a releasing position, and when located in the locking position, the end body (633〇 is compressed) The elastic body (632〇, such that the elastic body (632〇 loses elasticity) is used to make the resisting body (63^) locked in the blocking position and cannot move, and when the end body (633〇 is located in the release) In the position, the elastic body (632〇 is returned to be elastic, and the resisting body is allowed to be moved (the 631 is moved between the opening and the blocking position). Of course, the embodiment is only specific to the creation. As a feasible example, the scope of the request for protection in this case is not limited to it, but should be based on the scope of the patent application. The scope of effect is the protector of the case.
