In the recovery mechanism portion Sb, the movable pulley 21 is pulled up to the upper side while pulling the weight 23. The pulling speed of the movable pulley 21 and the weight 23 is the lay of the pulling speed v of the leads 2 and 3. The weight 23 has a low height in the seated state, but the height is increased in the suspended state. In other words, the initial weight of the moving pulley 21 is not improved. However, as the movable pulley 21 continues to rise, the weight 23 is increased and the speed is increased at the same speed as the movable pulley 21. 1357826 Shot by the hitting force! When the flying energy and the counterweight are used to increase the energy balance, the 'slammed ball 1 temporarily suspends the movement' and loses its weight. • With the counterweight 23 falling, the shot 1 is flying in the air to the original position. When the bottom surface of the weight 23 abuts on the placement surface I, the weight 23 is deformed, and the impact force is absorbed by the moving distance J. * The impact force is absorbed by the bottom of the wheel 21, and the weight 23 is seated on the placement surface j. Since the weight 23 is further changed to the suspended state, the lead 2, the 3rd-year-old brewing force, the ridge-like portion and the towel can be hit, and the (4) wire is in a stationary state. (Efficacy) If you hit the ball in accordance with the hitting practice device S, the hit ball will not be shaken after being hit and returned to the original position, and will immediately stand still, ready for the next hit. In addition, the structure is simple and the production cost is low. (Modification) Although the recovery mechanism Sb of the first embodiment is a single movable pulley system 5, it is also possible to adopt a configuration having two or more movable pulley systems. Figs. 5 and 6 show an example of a recovery mechanism portion Sb formed by two movable pulley systems. In the drawings, components equivalent to those of the foregoing embodiment are denoted by the same reference numerals, and additional pulleys 30, 3 are attached to the pulley 32. The movable pulley system 5a is formed by a fixed pulley 20 and a movable pulley 2, and the movable pulley system 5b is formed by a fixed pulley 31, a movable pulley 32, and a fixed point ρ. As shown in the figure, the movable pulleys 21 and 32 are connected via a connecting rod 34, and are integrally formed and operated under the upper 1357826. The upper and lower movements of the connecting rod 34 are guided by the guide post 35. The connecting rod is a rod-shaped body having a rectangular cross section, and the roller 34a is disposed at both end portions. The guide post 35 has a cross section in the shape of a sub-shape which is vertically erected and guides the roller 34a into the groove portion 35a thereof. • The counterweights 23 are common, but may be separately arranged. In this example, although the lengths of the leads 2 and 3 are longer, the responsiveness of the upper and lower velocities is 1/4V. Further, in the first embodiment, the sand material 26 is enclosed in the movable bag 25 so that the weight 23 has a cushioning action, but an additional magnet may be employed. Fig. 7 shows the form of such a magnet. In the figure, ml is a magnet which is fixed to the bottom of the movable sand bag, m2 is another magnet which is embedded in the ground, and 37 is a rubber pad which is laid on the surface of the floor portion I. The magnet ml and the lanthanum are attracted to each other. (Embodiment 2) Figs. 8 to 9 show the hitting practice device si of the second embodiment. The striking mechanism portion Sa of the hitting practice device S1 and the movable sheave of the return mechanism portion Sb are the same as those of the first embodiment, but the pullback mechanism 6A adopts another form. The pullback mechanism 6A is mainly configured such that one end is coupled to a coil spring 42 that is coupled to the lower end of the connecting rod 40 that is coupled to the movable sheave 21, and the other end of the coil spring 42 is fixed to the floor portion I at a fixed point z. The coil spring 42 employs a so-called tension spring to move the lowermost position of the pulley 21, which is in a state of a plurality of pretensioning forces. The connecting rod 4 has a specific diameter and rigidity. 17 1357826 A buffer mechanism 44 is attached to the connecting rod 40. That is, the buffer mechanism 44 is formed by the resistor body 45 that is preliminarily pulled from the connecting rod 40 and the container portion that houses the resistor body 45. Specifically, the resistor 45 is formed by the wrist portion 47 and the impedance plate, and one end of the wrist portion is rigidly joined to the pull rod 4Q, and the impedance disk 48 is fixedly disposed. The impedance disk 48 turns over the independent form and the shape of the annulus. Figure 9 shows the shape of the hole, 48a of the hole that you wear. It is preferable to arrange the backstop_ on the back of the impedance disk 48 on all or part of the circular hole 48a, but this is not an essential requirement. The illustration is an example and does not exclude others that can achieve the equivalent functions described above. The container portion 46 has a hole 46a in the center thereof, and a coil spring 42 is inserted through the hole gamma. The coil spring 42 is freely extendable. For each thief. The M6 is filled with water w, and the impedance disk 48 of the impedance body milk is dispensed at a fixed position to make it into the water to a certain depth. (Action) In the fixed state, the yo-ring 21 of the riding age is located at the lowest position, and the coil spring 42 has a pre-tensioning force. The smashing of the smashing smashing, 2, 3, and the singularity of the snails from the snails of the snails are not to be shaken by the weak external force such as the wind. That is to say, the lead wires 2, 3 are the hitting mechanism of the hitting mechanism # Sa 15 and the 16 phase, and the state is still fixed. In the operating state, the pull-out of the leads 2, 3 caused by the hitting of the hitting ball 2 is raised to the upper side, and the coil spring is stretched. Since the moving pulley 1357826 21 is increased, the impedance disk 48 of the resistor 45 can be increased from the water w, but its resistance is small. • When the resistance force (force) of the lifting force of the idler 21 reaches the balance, the hitting ball 1 temporarily stops moving, and the secondary spring 42 contracts with a specific contraction force. At the same time, the movable pulley 21 also moves downward, and the lead wires 2, 3 are pulled back to the initial position, and the shot 1 is swung in the air to the initial position. As the moving pulley 21 descends, the impedance of the resisting body 45 hits the water surface, causing the reverse valve φ to close the valve 49 and sinking into the water W with a large resistance. Before the moving pulley 21 reaches the lowest level k, the force is absorbed by the residual force, and the moving pulley 21 is still at the lowest position. The coil spring 42 still maintains the tensile force and applies a force to the leads 2, 3 to stabilize the hitting ball in the striking mechanism portion Sa and keep it in a stationary state. (Effect) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In addition, the buffering characteristics are clearer than in the first embodiment, and the setting operation is relatively simple. (Modification) I. The embodiment 2 has a spiral force. The shroud can be placed in a horizontal (horizontal) configuration. At this time, the buffer mechanism may use other means such as a high-profile material without using water. 1357826 Fig. 10 to Fig. 16 show the batting practice device S2 of the third embodiment. In the figure, components equivalent to the previous examples 1 and 2 use the same symbols. • As shown in the figure, the hitting practice device S2 is divided into the upper lead 2 by the shot 1 and the upper part of the body is below the line 3. The first half of the shot 1 and the upper lead 2 and the lower lead 3 constitute a striking mechanism portion, and the rear half of each of the upper lead 2 and the lower lead 3 constitutes a return mechanism portion. The recovery mechanism portion washes the movable pulley system 5 and the pullback mechanism 6B' to perform a specific φ pullback function with the lead wires 2, 3 being pulled out. Therefore, the hitting practice device S2 adopts a form in which the horizontal striking and the spring spring are biased, and the return mechanism of the upper and lower leads is independently washed. That is, Fig. 10 shows the configuration (partially omitted) of the side direction of the device S2, and shows a fixed state. In Fig. 10, the return mechanism portion Sb is displayed in the vertical direction, but is actually arranged to be displayed.帛U mesh wire slightly installs the frontal touch of S2, and the fine action state. In the 11th U, the recovery mechanism unit Sb scale mechanism unit & y is displayed in parallel, but is actually located behind the paper. In the drawings, the ceiling portion H and the secret portion are configured to be integrated, but the frame (the casing) is formed as a whole. Hereinafter, the special persuasion of the hitting practice device S2 will be mainly described. Refer to Figure 10 to Figure 13 for the fa mechanism. The hitting mechanism Sa is shouting on the fixed pulley 15A of the H-shaped part of the ceiling and the fixed pulley m fixed to the lower part of the secret part or the lower part of the casing. The above-mentioned 20 1357826 embodiment is used. The fixed pulley 15A fixed to the ceiling portion is configured to allow lateral shaking so as to allow lateral displacement of the shot 1 . Specifically, the fixed pulley 15 is a so-called rocking type, and the pulley 15c, the groove 15d around the pulley 15c, the shaft 15e that can freely rotate the holding pulley i5c, and the holding frame 15f of the holding shaft 15e are fixed. The mounting rod I5g of the ceiling portion η is configured by a rotating shaft 15h interposed between the mounting rod 15g and the holding frame i5f. • The same fixed pulley 16A fixed to the floor portion I adopts a configuration that allows lateral shaking to allow lateral displacement of the shot 1 . The fixed pulley 16A is configured by a fixed pulley 15A that is reversed in the vertical sequence, and is formed by a pulley, a groove, a shaft, a holding frame, a mounting rod, and a rotating shaft. Refer to FIG. 1G, FIG. 11, and FIG. 14 to FIG. 16) The recovery mechanism portion Sb is formed by the movable pulley system 5 and the pullback mechanism 6β, which is the same as the above-described embodiment, but is characterized in that it is combined with the upper bow. The recovery mechanism of the 1 line 2 linkage and the recovery mechanism of the linkage with the lower spring lead 3 are required to be independently arranged. The spring spring biasing mechanism is required for the pullback mechanism 6b. The upper lead 2 pure finance department does 3 series with the same composition, if not specified, and this is the cabinet. The movable pulley system of the recovery machine between the two-wire 2 system and the lower lead 3 system is the same as that described above. Technique ^#^ (Refer to Fig. 14 to Fig. 16) 1357826 In this embodiment, the return mechanism Sb is characterized by a pullback mechanism 6B. The pullback mechanism 6B is a suspension that is suspended by the movable pulley 21. The spring is loaded on the weight portion 7 of the suspension member 70, and the weight portion 71 is placed on the weight portion 71, and the spring-loaded elastic pull-back device 75 is formed. The spring-loaded pull-back device 75 is used. It is fixed to the _ part I or the casing while being pulled in with a certain charm* to the stretched member % fixed to the bottom surface of the weight portion 71. (suspension 70, weight portion 71, stopper 72) The suspension member 70 is connected to the shaft portion of the movable pulley 21 of the movable pulley system 5, and the suspension weight portion/weight portion 71 is supported by the bottom plate 71a and the single body. Or a plurality of thin cutting boards. The flying state of the hit ball can be changed by superimposing a single or a plurality of thin cutting plates 71b to adjust the weight. The thin cutting plate 71b is firmly fixed to the bottom plate 7''. The weight portion 71 does not need to be a heavy object or a lighter one, but mainly adjusts the load, and even contributes to the stop function of the stopper 72. ,

That is, in the figure, 77 is the guide post, so that the sliding or rotating component mounted on the side of the weight portion 71 is redundantly attached to the guide post 77. Further, the guide post 77 may be fixedly disposed between the ceiling portion η and the floor portion I, or may be fixedly disposed on the casing to form a part of the fixing system. The stopper 72 belongs to the fixing system. In the present embodiment, it is fixed to the guide post and disposed in the vicinity of the _ section J. The stopper 72 is used to prevent the athlete of the weight portion η from being a hard f-like buffer. 22 1357826 (stretching member 74, spring spring type pulling device 75) One end of the stretching member 74 is fixed to the bottom surface of the weight portion 71, and the other end portion is pulled into the spring spring type pulling device 75. It is fixed to a winding drum to be described later. In the positional state, it is pulled into the spring-loaded pull-back device 75. The spring-loaded pull-back device 75 is fixed to the rotating shaft 8 pivotally connected to the barrel 80 by a barrel 8 and as shown in Figs. 15 and 16 The stretching member on the rotating shaft 81 is wound around the drum 82 and the spring spring 83. Further, the rotating shaft 81 can be configured to be insulated from the barrel 8〇. In the positioned state, the stretching member 74 is wound around the stretching drum of the stretching member. The spring spring 83 is formed by winding a plurality of thin plate-shaped spring plates in a spiral shape, and one end thereof is fixed to the inner wall of the barrel 8 directly or via a mounting protrusion 85, and the other end is directly or mounted. The protruding portion 86 is fixed to the rotating shaft 81. The spring spring 83 is in a wound state in a state of being positioned, and is in a state of accumulating energy.
